Özet

The aim of study was to evaluate the effects ontarget volume (brain) and lens doses with different treatment plannings in patients who received whole brain radiotherapy because of brain metastases. The system tomography scans of 14 patients at 0.5 cm intervals, were transferred to three-dimensional treatment planning computer and the normal tissues and target volumes were outlined. Seven different treatment plannings were done for each patient. Plan I: Angled blocked plan; Plan II: Non-angled blocked plan; Plan III: Helmet plan; Plan IV: Blocked plan with the inferior border at the inferior orbital ridge; Plan V: Angled unblocked plan; Plan VI: Non-angled unblocked plan; Plan VII: Conventially planned non-angled unblocked plan. Brain and lens minimum, maximum and mean doses and brain V95 and D95 doses were recorded for each plan using dose-volume histograms.
